No experience with this specific chip but the interface is CNC standard opto-isolated step and direction. One pin for direction and one pin for step, send a pulse on step and it moves in the direction defined by the polarity of the direction pin.It has microstepping as well, which will require that you multiply by this number of steps...

The TB6560 is about the only single-chip stepper driver I've seen that can actuallyhandle 2A or more, due to the package being heatsink-mounted. It willstill run hot, adding some forced-air ventilation may be wise.

Note that many 2.2A motors are only about 1 ohm winding resistance andthe TB6560 itself is 0.7 ohms, so 40% of your power is wasted in the chip.

Normally a high current stepper driver uses discrete MOSFETs and getsits series resistance down to 0.05 ohms or less, meaning no heatsinkingis needed. However such a driver needs 8 MOSFETs and various ancilliarycomponents... Gets expensive.
